Product Description
Broadcom ACNU-4803-000E is a high-performance optocoupler designed for demanding industrial applications that require robust isolation and fast signal transmission. Using a surface mount SSO8 package, it provides an isolation voltage of 5000V, suitable for protecting electronic circuits from high voltage surges while ensuring reliable logic transfer.
This optocoupler supports a maximum forward voltage of 1.85V and features an 8-pin SSO8 package that is compact and auto-insertable, ideal for high-density PCBs. The typical rise and fall times are 6ns, enabling rapid switching in real-time control systems. With an industrial operating temperature range from -40°C to 105°C, the ACNU-4803-000E is engineered for use in harsh environments and critical infrastructure setups.
It offers positive output type with totem pole output and guarantees performance with Vcc from 4.5V to 30V, allowing flexible integration into a variety of logic circuits. Its high common-mode rejection (minimum 50 kV/μs at VCM = 1500 V) ensures stable operation even in noisy environments, making it suitable for IPM, inverter, motor drive, IGBT/MOSFET gate drive, and digital isolation interfaces.
The ACNU-4803-000E minimizes pulse width distortion to provide accurate signal propagation with propagation delays (TPLH/TPHL) of 120ns/150ns maximum. It has a minimum LED drive current of 12mA, and is certified to CSA, IEC 60747-5-5, and UL1577 safety standards, supporting compliance and reliability requirements in highly regulated sectors.
This surface mount optocoupler addresses the needs of industrial automation, HVAC, motor control, and digital isolation applications, serving as a key component in systems requiring safe and precise transmission of digital signals across isolation barriers.
Suitable for IPM interface isolation, inverter systems, AC and brushless DC motor drives, isolated gate drive applications, and general digital isolation. Compact SSO8 form factor with 11-mm creepage and 10.5-mm clearance ensures easy PCB integration.
Performance specified for common IPM applications, providing reliability throughout the industrial temperature range. Browse more industrial Optocouplers and Broadcom category products on EnvMart to find reliable solutions for electronics, automation, and power management needs.
